Abstract
A color-reproduction system is provided. The system includes an image-content-analysis unit that analyzes the color distribution of pixels that constitute an inputted image, a parameter-prediction unit that predicts scaling parameters based on the attribute information on the pixels, the color distribution, and the image size information, and a luminance-chroma-determination unit that determines the final luminance and chroma of the pixels using the predicted parameters.
Claims17
A color-reproduction system adapted to transfer an original image in a first display to a destination image in a second display, the system comprising:
- a processor to control each of the following units;
- an image-content-analysis unit that analyzes color uniformity of an image content based on hue difference using at least one processor;
- a parameter-prediction unit that predicts luminance and chroma scaling parameters based on attribute information of the pixels, a color uniformity, and image size information;
- and
- a luminance-chroma-determination unit that determines a final luminance and chroma of the pixels using the predicted luminance and chroma scaling parameters,
- wherein the attribute information comprises luminance, chroma and hue information of the pixels;
- the color uniformity represents a percentage value for each pixel of the image for a hue range;
- and the image size information comprises a subtending viewing angle of the first display and the second display.
